The purpose of this study was to examine the psychometric properties of the Grit-Original scale within the Netherlands. The Grit-O scale was subjected to a competing measurement modeling strategy that sequentially compared both independent cluster model confirmatory factor analytical- and exploratory structural equation modeling approaches. The results showed that both a two first order, bi-factor structure as well as a less restrictive two factor ESEM factorial structure best-fitted the data. The instrument showed to be reliable at both a lower- and (...) upper-level limit. However, measurement invariance between genders could only be established for the B-ICM-CFA model. Finally, concurrent validity was established through relating the GRIT-O to task performance. The linear use of the Grit-O scale should therefore carefully be considered. (shrink)

In more than half of its states, the USA has recently passed or proposed legislation to limit or ban public educational curricular reference to race, gender, sexuality, or other identity topics. The stated justifications for these legislative moves are myriad, but they share a foundational claim; namely, these topics are asserted to be politically and socially divisive such that they ought not to be included within state-controlled schools. In this paper, we consider the claims of divisiveness regarding these topics and (...) explore whether, even if taken in good faith, the popular versions of these arguments and actions are epistemically defensible. We conclude that these bans are an epistemic injustice and therefore argue for their end. The article proceeds to consider the foundational claims of epistemic injustice, followed by the invocation of epistemic standards by which the arguments for these bans can be evaluated. The article then transitions to a close application of these standards, weighing the possible epistemic gains and losses. Before concluding, we consider objections and explore the social and epistemic significance of these issues. (shrink)

Very few scientists today question the fact that information, together with matter and energy, is one of the three constructs forming the ontology of the universe. However, there is still a long way to go before in order to establish the interrelations between information and energy and information and matter, as Einstein did between matter and energy. In this paper, after introducing the energy, matter, information model, which covers the three constructs and their relationships, we illustrate real examples—two qualitative and (...) two quantitative—of the interrelations between energy and information. This closes the open question with respect to the interrelationship between energy and information. (shrink)

Processing data streams arriving at high speed requires the development of models that can provide fast and accurate predictions. Although deep neural networks are the state-of-the-art for many machine learning tasks, their performance in real-time data streaming scenarios is a research area that has not yet been fully addressed. Nevertheless, much effort has been put into the adaption of complex deep learning (DL) models to streaming tasks by reducing the processing time. The design of the asynchronous dual-pipeline DL framework allows (...) making predictions of incoming instances and updating the model simultaneously, using two separate layers. The aim of this work is to assess the performance of different types of DL architectures for data streaming classification using this framework. We evaluate models such as multi-layer perceptrons, recurrent, convolutional and temporal convolutional neural networks over several time series datasets that are simulated as streams at different speeds. In addition, we evaluate how the different architectures react to concept drifts typically found in evolving data streams. The obtained results indicate that convolutional architectures achieve a higher performance in terms of accuracy and efficiency, but are also the most sensitive to concept drifts. (shrink)

Background: The coronavirus disease 2019 pandemic is impacting the delivery of healthcare worldwide, creating dilemmas related to the duty to care. Although understanding the ethical dilemmas about the duty to care among nurses is necessary to allow effective preparation, few studies have explored these concerns. Aim: This study aimed to identify the ethical dilemmas among clinical nurses in Spain and Chile. It primarily aimed to identify nurses’ agreement with the duty to care despite high risks for themselves and/or their families, (...) describe nurses’ well-being and describe the associations between well-being and the duty to care. Research design: Cross-sectional self-reported anonymous data were collected between May and June 2020 via electronic survey distribution. Ethical considerations: The Institutional Ethical Review Committees in both countries approved the study. Findings: In total, 345 clinical nurses answered the primary question about the duty to care for the sick. Although in the total sample 77.4% agreed they have a duty to care for the sick, significant differences were found between the Spanish and Chilean samples. Overall, 53.6% of the nurses reported low levels of well-being; however, among those reporting low well-being, statistically significant differences were found between Spanish and Chilean nurses as 19.4% and 37.8%, respectively, disagreed with the statement regarding the duty to care. Discussion: Participants in both countries reported several ethical dilemmas, safety fears, consequent stress and low well-being. These results suggest that prompt actions are required to address nurses’ ethical concerns, as they might affect their willingness to work and psychological well-being. Conclusion: Our findings shed light on the ethical dilemmas nurses are facing related to the duty to care. Not only has the coronavirus disease 2019 pandemic given rise to ethical challenges, but it has also affected nurses’ well-being and willingness to work during a pandemic. (shrink)

Despite abundant evidence associating CD38 overexpression and CD4 T cell depletion in HIV infection, no causal relation has been investigated. To address this issue, a series of mechanisms are proposed, supported by evidence from different fields, by which CD38 overexpression can facilitate CD4 T cell depletion in HIV infection. According to this model, increased catalytic activity of CD38 may reduce CD4 T cells’ cytoplasmic nicotin‐amide adenine dinucleotide (NAD), leading to a chronic Warburg effect. This will reduce mitochondrial function. Simultaneously, CD38's (...) catalytic products ADPR and cADPR may be transported to the cytoplasm, where they can activate calcium channels and increase cytoplasmic Ca2+ concentrations, further altering mitochondrial integrity. These mechanisms will decrease the viability and regenerative capacity of CD4 T cells. These hypotheses can be tested experimentally, and might reveal novel therapeutic targets. (shrink)

Unlike birds and mammals, reptiles are commonly thought to possess only the most rudimentary means of interacting with their environments, reflexively responding to sensory information to the near exclusion of higher cognitive function. However, reptilian brains, though structurally somewhat different from those of mammals and birds, use many of the same cellular and molecular processes to support complex behaviors in homologous brain regions. Here, the neurological mechanisms supporting reptilian cognition are reviewed, focusing specifically on spatial cognition and the hippocampus. These (...) processes are compared to those seen in mammals and birds within an ecologically and evolutionarily relevant context. By viewing reptilian cognition through an integrative framework, a more robust understanding of reptile cognition is gleaned. Doing so yields a broader view of the evolutionarily conserved molecular and cellular mechanisms that underlie cognitive function and a better understanding of the factors that led to the evolution of complex cognition.

A post-Darwinian conception of feeling and emotion is necessary in order to better appreciate the embodied, personalized, and socialized nature of cognition in Peirce's late 1860's Journal of Speculative Philosophy "cognition series." Peirce both distinguishes between and renders synonymous the terms "feeling" and "emotion," a fruitful ambiguity that underscores how easily one's process of thinking can be influenced by idiosyncratic concerns. My reading of this series is a proactive one in which I employ the work of Antonio Damasio to highlight (...) the implicit post-Darwinian embodiment themes in this series. (shrink)

This article uses Peirce's Critical Common-sensism to conduct social critical inquiry into racism and “colorblindness” in the U.S. I argue that “colorblindness” discourse - in its sincere, but naïve form - is an enactment of paper-doubt, where racist common-sense beliefs are supposedly eradicated, but still function unintentionally. I offer a Peircean challenge to the common dismissal of people of color's testimony regarding the prevalence of racism. Since people of color experience racism-based secondness often not experienced by whites, their testimony must (...) be embraced as indispensable to the elimination of racist belief-habits. (shrink)

L’aphorisme sur lequel s’ouvre la préface du livre : « Tant vaut la femme, tant vaut la famille et la société » retrace parfaitement le rôle que la société du XIXe siècle entend accorder aux femmes.

C’est cet éloge de la ménagère œuvrant au bien-être de (...) son foyer et de la nation toute entière... (shrink)

Turing was an exceptional mathematician with a peculiar and fascinating personality and yet he remains largely unknown. In fact, he might be considered the father of the von Neumann architecture computer and the pioneer of Artificial Intelligence. And all thanks to his machines; both those that Church called “Turing machines” and the a-, c-, o-, unorganized- and p-machines, which gave rise to evolutionary computations and genetic programming as well as connectionism and learning. This paper looks at all of these and (...) at why he is such an often overlooked and misunderstood figure. (shrink)

It has recently been argued that normative considerations play an important role in causal cognition. For instance, when an agent violates a moral rule and thereby produces a negative outcome, she will be judged to be much more of a cause of the outcome, compared to someone who performed the same action but did not violate a norm. While there is a substantial amount of evidence reporting these effects, it is still a matter of debate how this evidence is to (...) be interpreted. In this paper, we engage with the three most influential classes of explanations, namely, (a) the Norm‐Sensitive Cognitive Process View, (b) the Normative Concept View, and (c) the Pragmatics View. We will outline how these theories explain the empirical results and in what ways they differ. We conclude with a reflection on how well these strategies do overall and what questions they still leave unanswered. (shrink)

In this article, we report a study in which 109 research-active mathematicians were asked to judge the validity of a purported proof in undergraduate calculus. Significant results from our study were as follows: (a) there was substantial disagreement among mathematicians regarding whether the argument was a valid proof, (b) applied mathematicians were more likely than pure mathematicians to judge the argument valid, (c) participants who judged the argument invalid were more confident in their judgments than those who judged it valid, (...) and (d) participants who judged the argument valid usually did not change their judgment when presented with a reason raised by other mathematicians for why the proof should be judged invalid. These findings suggest that, contrary to some claims in the literature, there is not a single standard of validity among contemporary mathematicians. (shrink)

A well known theorem proved by J. Paris and H. Friedman states that BΣn +1 is a Πn +2-conservative extension of IΣn . In this paper, as a continuation of our previous work on collection schemes for Δn +1-formulas , we study a general version of this theorem and characterize theories T such that T + BΣn +1 is a Πn +2-conservative extension of T . We prove that this conservativeness property is equivalent to a model-theoretic property relating Πn-envelopes and (...) Πn-indicators for T . The analysis of Σn +1-collection we develop here is also applied to Σn +1-induction using Parsons' conservativeness theorem instead of Friedman-Paris' theorem.As a corollary, our work provides new model-theoretic proofs of two theorems of R. Kaye, J. Paris and C. Dimitracopoulos : BΣn +1 and IΣn +1 are Σn +3-conservative extensions of their parameter free versions, BΣ–n +1 and IΣ–n +1. (shrink)

ZusammenfassungSystemmedizinische Ansätze zeichnen sich durch die Integration großer Datenmengen aus vielfältigen Datenquellen aus und führen systembiologische und medizinische Forschungsansätze mit informationswissenschaftlichen Methoden und prädiktiven Verfahren mathematischer Modellierung zusammen. Hieraus resultiert eine enge Kooperation von Ärzten und Naturwissenschaftlern, wobei insbesondere die Expertise nicht-ärztlicher Forscher zunehmend an Bedeutung für die Datenaufbereitung und -interpretation gewinnt. Aus ethischer Perspektive wirft diese Entwicklung Fragen nach der konkreten Gestaltung einer systemmedizinischen Zusammenarbeit sowie möglichen Rollenveränderungen und neuen Verantwortungszuschreibungen an Ärzte und nicht-ärztliche Forscher auf. Um diese Fragen (...) mit Blick auf die Erfahrungen und Perspektiven der beteiligten Akteursgruppen zu beleuchten, führten wir eine qualitative Interviewstudie mit Ärzten und nicht-ärztlichen Forschern aus unterschiedlichen systemmedizinischen Kontexten durch. Aus dem Interviewmaterial ließen sich zwei Konzeptionen von Systemmedizin rekonstruieren. Die erste ist durch eine eindeutige arbeitsteilige Rollentrennung zwischen Ärzten und Forschern charakterisiert: Der Forscher fungiert als Dienstleister, der Arzt als translationaler, interdisziplinär ausgerichteter Mediziner. Die zweite zeichnet sich durch eine weitreichende Aufhebung der Rollentrennung von Ärzten und Forschern aus: Die Berufsgruppen agieren als interdisziplinäres Team mit einer engen wechselseitigen inhaltlichen und methodischen Zusammenarbeit der Akteure. In beiden Konzeptionen werden Rollenkonflikte von Ärzten und Forschern deutlich, die insbesondere auf die Diskrepanz zwischen dem Arzt- und Forscherethos und die mit ihnen je verknüpften spezifischen Handlungsnormen und Ziele zurückzuführen sind. Ferner besteht mit Blick auf die dem Arzt und Forscher jeweils zukommende Verantwortung gegenüber Patienten vielfältiger normativer Klärungsbedarf, insbesondere hinsichtlich der Frage, welche Verantwortung den Akteursgruppen gerechtfertigter Weise zugeschrieben werden kann. Diesbezüglich erscheint eine Differenzierung von versorgungsnäheren und grundlagenforschungsorientierten Arbeitsfeldern angeraten. (shrink)

Headache disorders can be considered as the predominant neurological condition. In the field of neurological diseases, migraine was estimated to cost a total of €27 billion per year for the loss through reduced work productivity in the European Community. Medical data and information in turn provide knowledge based on which physicians make scientific decisions for diagnosis and treatments. It is, therefore, very useful to create diagnostic tools to help physicians make better decisions. This paper is focused on a new hybrid (...) clustering system combining analytic hierarchy process and weighted fuzzy c-means clustering method for diagnosing children with primary headache disorder. The proposed three-stage hybrid diagnosing system is tested on data set collected from hospitalized children in the Clinical Centre of Vojvodina, Novi Sad, Serbia. (shrink)

By a theorem of R. Kaye, J. Paris and C. Dimitracopoulos, the class of the Πn+1-sentences true in the standard model is the only consistent Πn+1-theory which extends the scheme of induction for parameter free Πn+1-formulas. Motivated by this result, we present a systematic study of extensions of bounded quantifier complexity of fragments of first-order Peano Arithmetic. Here, we improve that result and show that this property describes a general phenomenon valid for parameter free schemes. As a consequence, we obtain (...) results on the quantifier complexity, finite axiomatizability and relative strength of schemes for Δn+1-formulas. (shrink)

Smart grids are rolling out internationally, with the United States nearing completion of a significant USD4-plus-billion federal program funded under the American Recovery and Reinvestment Act. The emergence of smart grids is widespread across developed countries. Multiple approaches to analyzing the benefits of smart grids have emerged. The goals of this white paper are to review these approaches and analyze examples of each to highlight their differences, advantages, and disadvantages. This work was conducted under the auspices of a joint U.S.-China (...) research effort, the Climate Change Working Group Implementation Plan, Smart Grid. We present comparative benefits assessments of smart grid demonstrations in the U.S. and China along with a BA of a pilot project in Europe. In the U.S., we assess projects at two sites: the University of California, Irvine campus, which consists of two distinct demonstrations: Southern California Edison’s Irvine Smart Grid Demonstration Project and the UCI campus itself; and the Navy Yard area in Philadelphia, which has been repurposed as a mixed commercial-industrial, and possibly residential, development. In China, we cover several smart-grid aspects of the Sino-Singapore Tianjin Eco-city and the Shenzhen Bay Technology and Ecology City. In Europe, we look at a BA of a pilot smart grid project in the Malagrotta area west of Rome, Italy, contributed by the Joint Research Centre of the European Commission. The Irvine sub-project BAs use the U.S. Department of Energy Smart Grid Computational Tool, which is built on methods developed by the Electric Power Research Institute. The TEC sub-project BAs apply Smart Grid Multi-Criteria Analysis developed by the State Grid Corporation of China based on the analytic hierarchy process with fuzzy logic. The B-TEC and TNY sub-project BAs are evaluated using new approaches developed by those project teams. JRC has adopted an approach similar to EPRI’s but tailored to the Malagrotta distribution grid.

If Catullus' poems as we have them faithfully reproduce their order in the original roll or rolls, and if that order reflects a design of the poet's, then the last piece in our manuscripts naturally merits close attention. But even one who has vigorously upheld these hypotheses writes: ‘it is tempting to suppose that the poem is a spurious addition, attached after the publication of the collection; Catullus may indeed have written it, but not wanted to include so illepidus (...) a piece of versification in his published works’. Nor has the poem attracted much interest in its own right; it seems to be generally considered just another slice of biography, and as such hardly susceptible of a poetic meaning. The remarks which follow try to show that it has one, and perhaps also a significant position. (shrink)

Jeder Mensch steht in einem mehr oder weniger klaren Verhältnis zur eigenen Person, zu dem, was man auch das Selbst nennt. Hierbei spielt der Raum eine entscheidende Rolle - denn der Mensch ist nicht begreifbar ohne den Ort, an dem er sich aufhält. Matthias C. Müllers raumtheoretisch fundierte Neubeschreibung des philosophischen Großthemas Selbstheit bzw. Subjektivität zeigt nicht nur, daß menschliches Dasein nicht ohne Bezug auf das Wohnen im Raum begriffen werden kann, sondern auch, daß eigentlich nicht der Mensch den Raum (...) hervorbringt, sondern vielmehr der Raum den Menschen.
